Voting was tight, but WhatsApp edged out the competition with just under 31% of the vote. Despite being the only service in the roundup with a subscription cost, its combination of rich multimedia messages and threaded conversations to multiple recipients may have had something to do with its popularity. Coming in at second place was Google Voice, with just under 23% of the vote. GroupMe came in third with 21.5%. Bringing up the rear: BlackBerry Messenger with just over 15.3%, and Facebook-acquired Beluga with 9.6% of the vote.
